Can viruses horizontally transfer genes co-packaged from one host to another?

It has long been known that viruses, in addition to their own genomes, encapsidate extraneous nucleic acids. Although this phenomenon has been verified in the prokaryotic world, in eukaryotes, the significance of these alternative nucleic acids could just be trivial, or, quite possibly evolutio...

Mycoplasma - adhesion of symbiont infection structure to host

This scanning electron micrograph shows mycoplasma (colorized pink), a genus of bacteria that lack a cell wall. Without a cell wall they are unaffected by many common antibiotics, such as penicillin, or other beta-lactam antibiotics that work by targeting cell wall synthesis. These mycoplasma ar... Read More

Strange life found in underwater caves - Biologists finding new microbes totally unknown elsewhere on Earth

Clues to how life evolved, not only on this planet but also possibly on alien worlds, might be found in underwater caves in the Bahamas, researchers say.

The caves in question are called "blue holes," so-named because from the air, their entrances appear circular in shape, with different shad... Read More

The search for life's stirrings

Scientists studying how life arose on Earth are stumped by several key steps in that eventual process, but a Harvard scientist studying the earliest cells says that seemingly intractable problems in this field have sometimes proved to have simple, even elegant solutions.

Those pondering the e... Read More

Modeling microbes to manage carbon dioxide

In the past decade, microbiologists began realizing that communities of microbes process energy and materials, which affects their environments. To understand how microbial communities function in a natural ecosystem, Pacific Northwest National Laboratory scientists developed a novel kinetic mod... Read More

Oral bacterial colonies, including Capnocytophaga and Aggregatibacter

This color-enhanced photomicrograph shows different species of bacteria that cause dental plaque - a colorless film that forms on teeth caused by the growth of bacterial colonies. Plaque develops naturally, and in most cases can be easily removed with regular brushing. However, if left it can ha... Read More

Food Poisoning: Understanding How Bacteria Come Back from the 'Dead'

Salmonella remains a serious cause of food poisoning in the UK and throughout the EU, in part due to its ability to thrive and quickly adapt to the different environments in which it can grow. New research involving a team of IFR scientists, funded by BBSRC, has taken the first detailed look at ... Read More

Study shows electron-beam irradiation reduces virus-related health risk in lettuce, spinach

A team of scientists studying the effects of electron-beam irradiation on iceberg lettuce and spinach has had its research published in the February issue of the leading microbiology journal, Applied and Environmental Microbiology, said the study’s lead investigator.

The study quantified the ... Read More

Salmonella cases linked to watermelon

Watermelons could be the cause of five Scottish cases of salmonella which have been linked to a UK-wide outbreak, health officials have said.

Since the beginning of December, there have been 30 cases of the Salmonella Newport infection across the UK.

Four of the five infections in Scotland... Read More

I recently started reading a lot more papers than what I'm used to (school related) and I actually find it quite difficult to use them.


Of course it doesn't help that E... Read More
